My question is this, my '83 has an issue with idiling while in gear. It idles rough and stumbles some up until about 2000rpm, after that it smoothes out... although it occasionally stumbles some (rarely). I was just wondering if anyone has any idea what this problem is (it does it in 2 and 4wd if it matters). My other 2 subies have had manual transmissions and an early 80's Subie with an auto seems to be a rare bird. Any ideas on what's going on?
